Galaxy S25 Ultra: selected board evidence

Sources reviewed: 2026-10-18

Nine selected records from iFixit's Galaxy S25 Ultra board guide, which identifies 12GB LPDDR5X and a 256GB UFS package. Sales region, retail SKU, batch and exact model code are unstated. Samsung's US page supplies platform context, not proof that the examined unit was sold in the US. This selection excludes S25, S25+, S25 Edge and later generations.

• Processor branding and a factory are different answers

  Samsung names Snapdragon 8 Elite for Galaxy as the platform. That answers the processor question, but it does not identify the fabrication plant or packaging contractor for a particular chip. Treat design, physical manufacturing and final phone assembly as separate relationships. A list of chip vendors cannot fill those missing links by assigning their headquarters as factories.

• 12GB RAM and 256GB storage serve different jobs

  Working memory holds data for active tasks; persistent storage retains apps and files. Increasing one is not equivalent to increasing the other. Here the Micron and Samsung records identify separate roles in the pictured board selection. Compare the same capacity and region before generalizing its vendors to another handset; the US catalog is context rather than the sample’s sales receipt.

• A charging chip is not the battery manufacturer

  Analog Devices describes MAX77751 as a single-cell charger with USB-C detection. Cirrus describes CS40L26/26B as a haptic driver. These functions explain the difference between control electronics and the parts they drive. A charger cannot identify the battery-cell maker, and a haptic-driver label cannot identify the motor. Their capabilities alone also do not establish the phone’s enabled settings or measured performance.
